They care nothing about home owners or landlords, if they did these process would be clear cut 9 times in 10 and would never require a time extension. 

HUD doesn't care if you buy 3 on the same day! 

If you can find a 15% cap, who cares if its a 4 plex or a strip mall.

I have had nothing but problems with applicants trying to apply and get screened.I don't particularly care about the auction aspect but it would be nice to have a modern website for applications to submit documentation and tenants to pay rent and sign leases.Anyone happen to know of any service like that?

Don’t assume the tenant is taking care of it.

I would be careful going as far as .50 miles away.

I would personally pick option C.Place tenant myself and self manage for the following reasons:I don't like giving away 10% of my rents.No one is going to care about my property more than me.I have systems in place that allow my to self manage with minimal time.I have a great support staff that I can text when there is a repair that is needed.I rarely take calls from tenants and tell them to text me to keep from getting caught up in their drama.If they don't pay rent on time and it is a repetitive problem I file an eviction to train them they must pay on time or go somewhere else.They can pay rent with Zelle, paypal or deposit rent into my bank account (most deposit into my account)It is their job to pay rent on time I do not collect or chase rent it comes to me.My rental portfolio is very passive with little interaction required by me.

Both inspections happened w/in a week (though I’m sure timing is highly area dependent).I have a property manager who took care of everything so all of this was very seamless to me.

I have so damn many leads that I can't possibly take care of them all. 

In my case, there are major issues like roof replacement, siding, mold remediation, etc. and the house is vacant and in very poor shape, so there is no way any of these violations will be taken care by the seller.
